Four Most Common Types of Food Contamination


Biological Contamination

Germs in Fruits and Vegetables


Biological contamination is one of the common causes of food poisoning as well as spoilage. During biological contamination, the harmful bacteria spread on foods that you consume. Even a single bacterium can multiply very quickly when they find ideal growth conditions. Not just bacteria, but also their process of multiplying can be quite harmful to humans. The common places where you can find bacteria are:

  • Dust
  • Raw meat
  • The air
  • The human body
  • Pets and pests
  • Clothes of food handler
  • Kitchen clothes

The best way to avoid food contamination is by washing the food items with KENT vegetable and fruit cleaner and wash the kitchen cloths on a regular basis.

Physical Contamination

Chemical contaminants are one of the serious sources of food contamination. These contaminants can also lead to food poisoning. Pesticides present in fruits and vegetables are one of the main sources of contamination. In addition, kitchen cleaning agents, food containers made of non-safe plastic, pest control products also lead to food contamination. Though we make it a point to wash fruits and vegetables thoroughly, however, plain water can’t remove all the contaminants. This is where KENT Vegetable and Fruit Cleaner can help you out. The smart kitchen appliance uses ozone disinfection technology that removes contaminants from the surface of the fruits and vegetables to make it safe for consumption.


Many of us are not aware of cross contamination; however, this type of contamination can lead to a number of health problems. Cross-contamination takes place when pathogens are transported from any object that you use in the kitchen. Dirty kitchen clothes, unclean utensils, pests, raw food storage can lead to cross-contamination. Here are some of the ways to avoid cross-contamination:

  • Personal Hygiene- Thoroughly wash your hands and face when handling food. Coughing, sneezing or even touching your hair can lead to cross contamination
  • Utensils-Use separate utensils to prepare different types of foods. Avoid using the same chopping board and knife for ready to eat foods
  • Storing Food-Make sure raw foods don’t come in contact with ready to eat foods. Cover and store raw foods below cooked foods to prevent cross-contamination.

Disposing Waste-Make sure you store and seal garbage correctly to prevent cross-contamination. Clean and sanitize the waste bins to prevent infestation risk.
